Out of this World

NASA announced that September 2017 to September 2018 is A Year of Education on Station for the International Space Station (ISS), featuring a variety of education-related events for students and teachers. Astronaut Richard (Ricky) Arnold, a volunteer board member for the Project WET Foundation, will be the educator on board the ISS for the latter half of this year—from March to September 2018. Given Project WET’s connection with Ricky, the Project WET Foundation seized the opportunity to enhance educational activities relating to water and the ISS’s Year of Education on Station. For more information about these educational offerings see descriptions below.
